Fibers are like tiny little rods or tubes-much longer than they are wide. Just about any fiber that you can think of is a polymer. (I guess that if it's a metal, it's called a wire, not a fiber!). Fibers can be natural-from plant or animals, or synthetic-made by people.
Accessory uses and structures. (A) A structure or use which is clearly incidental to a principal structure or use, and is located on the same lot with the principal structure or use, is an accessory use. All accessory uses are subject to the restrictions in this section.
An accessory device is a non-implanted medical device (such as a ventilator, patient monitor) that is used to monitor or support the patient. 1  The strong, static magnetic field of the MRI scanner will pull on magnetic materials and may cause unwanted movement of the medical device. The radiofrequency energy and magnetic fields that change with time may cause heating of the implanted medical device and the surrounding tissue, which could lead to burns.
